2. 例文

/ The need for dead heads depends on the alloy being cast and the geometry of the mold cavity. For example, cast iron often needs very little in the way of dead heads, because graphite expansion during solidification may compensate for the shrinkage of the iron.

/ The first requirement is that the mold material must flow or be pliable enough to encapsulate the surface around the shape of the pattern.
